本发明涉及机械与密码复合锁具结构设计技术, 特别提供了一种使用 钥匙的机械式密码复合锁具。 背景技术
现有技术中, 典型的防盗锁具包含有如下几类: 第一类是用钥匙开启 的弹子式机械锁; 第二类是使用密码转盘和开门把手相配合的机械式密码 锁; 第三类是使用电子加密手段的密码锁。
以机械式的弹子锁和机械式密码锁为例进行说明如下: 传统的机械锁 保密性不够好, 通过直接破坏机械锁的弹子或者使用万能钥匙等辅助工具 可以比较方便地进行非正常状态的开启操作。 传统的转盘式密码锁的密码 锁核心部位通常比较靠近外部, 容易受到破坏; 如果釆用防止破环的机械 结构的话, 锁具本身的体积、 重量都相对较大, 因此不适合用在要求锁具 体积相对较小、 轻便灵活的情况。
人们期望获得一种结构相对简单, 保密性好, 技术效果更好的机械式 锁具。 发明内容 本发明的目的是提供一种技术效果更好的使用钥匙的机械式密码复合 锁具。
本发明具体提供了一种使用钥匙的机械式密码复合锁具, 其包含有弹 子锁芯模块, 所述弹子锁芯模块中具体包含安装有弹子且内部设置有钥匙 孔的锁体 9, 锁体 9的一端为钥匙进口端; 其特征在于:
所述使用钥匙的机械式密码复合锁具中除了弹子锁芯模块之外还包含 有下述组成部分: 机械密码模块、 拨动模块; 其中:
所述弹子锁芯模块和机械密码模块通过拨动模块连接起来;
所述弹子锁芯模块包含有锁体 9,其内部设置有钥匙插孔,所述机械密 码模块设置在弹子锁芯模块远离钥匙插入端一侧。 这样安排便于对所述机 械密码模块进行保护, 不易被人破坏。 本发明所述使用钥匙的机械式密码复合锁具还要求保护下数优选内 容: 所述使用钥匙的机械式密码复合锁具中的拨动模块具体构成如下: 可 动锁片 3、 拨盘 4, 其中:
可动锁片 3具体为片状结构, 其靠近钥匙插孔的一端与弹子锁芯模块 作周向固定, 其能够沿锁具轴线串动;
可动锁片 3到达远离钥匙插孔的极限位置时, 其与拨盘 4能相对周向 固定; 此时能够形成所述锁芯 12绕锁具轴向转动带动可动锁片 3转动, 可 动锁片 3带动拨盘 4转动, 拨盘 4带动机械密码模块动作的联动机构。 本发明所述使用钥匙的机械式密码复合锁具的进一步优选内容如下: 所述使用钥匙的机械式密码复合锁具中的机械密码模块具体由同轴的 1〜6 个锁片 6, 所述锁片 6的结构满足下述要求- 其主体部分具体为内部设置有圆孔的片状结构, 在片状结构的边缘处 设置有固定在该片状结构部分上的与所述使用钥匙的机械式密码复合锁具 同轴的空心圆筒结构, 所述锁片 6整体为边沿有缺口的盆状结构;
其按照盆沿部分直径由小到大依次沿着逐渐远离拨盘 4的方向布置, 所述的每相邻的两个锁片 6中, 距离拨盘 4越近的其盆沿外径越小, 所述 锁片 6沿着远离锁体 9的方向依次由大到小套装在一起;
拨盘 4的大头端外径尺寸小于最靠近拨盘 4的锁片 3盆沿的内径, 拨 盘 4的大头端能够套装在与其相邻的锁片 6盆沿内部。 所述使用钥匙的机械式密码复合锁具中的拨动模块具体还满足下述要 求: 拨盘 4设置在机械密码模块远离弹子锁芯模块的一侧;
所述使用钥匙的机械式密码复合锁具通过钥匙转动带动拨盘 4旋转, 然后按照距离锁体 9 由远及近的顺序依次动作, 最终达到使得距离锁体 9 最近的锁片 6最先通过上述传动动作调整到开锁状态, 而距离锁体 9最远 的锁片 6最后通过上述传动动作调整到开锁状态的顺序动作要求。
所述使用钥匙的机械式密码复合锁具中,在拨盘 4和与其相邻的锁片 6 的相互接触的侧面上, 设置有与锁具轴线基本等距的拨销 B;
当锁片 6为 2〜6片时, 在相邻的两个锁片 6的相邻的两个侧面上设置 有与锁具轴线基本等距的拨销 13。拨销 13用于当一个锁片 6主动转动时借 助于拨销 13拨动另一个锁片 6随之转动。 所述使用钥匙的机械式密码复合锁具中, 当锁片 6为 2〜6片时, 在相 邻的两个锁片 6之间设置有分隔止动垫片 7,所述分隔止动垫片 7为内部有 孔的片状结构, 内部圆孔内径不小于可动锁片 3宽度最宽处的尺寸;
所述使用钥匙的机械式密码复合锁具中, 弹子锁芯模块的主体为外径 相对较大的锁体 9,其内部设置有钥匙孔;锁体 9靠近锁片 6—侧设置有与 锁具同轴线的轴向凸台 901,该轴向凸台 901为空心管状结构,弹子锁芯模 块的锁芯 12设置在上述的轴向凸台 901内部并能绕锁具轴线转动;
所述弹子锁芯模块的锁芯 12靠近锁片 6—端设置有与可动锁片 3构成 二者周向固定的配合结构; 同时, 该配合结构与钥匙孔连通, 当钥匙孔中 有钥匙插入时, 插入的钥匙轴向顶紧可动锁片 3使其轴向串动并形成可动 锁片 3与拨盘 4的周向同步转动关系并进而实现开锁动作。 所述使用钥匙的机械式密码复合锁具中, 锁片 6设置在拨盘 2靠近锁 体 9的一侧;
所述拨动模块中的拨盘 4为分体结构, 其主体部分为内部有孔的片状 结构, 其内部圆孔内径不小于可动锁片 3远离弹子锁芯模块的宽度较小部 分的宽度, 其内部圆孔内径小于可动锁片 3靠近弹子锁芯模块的宽度较大 部分的宽度;
所述拨动模块中的拨盘 4还包含有空心或实心圆柱形结构的拨盘导柱 2, 所述拨盘导柱 2的外径小于拨盘 4内部圆孔内径; 所述使用钥匙的机械式密码复合锁具中的所述拨动模块中还设置有弹 簧 1 ,其具体安装在空心结构的拨盘导柱 2内部空腔中或者拨盘导柱 2外部; 弹簧 1具体为压簧, 弹簧 1远离弹子锁芯模块的一端在锁具轴线上的轴向 位置固定, 弹簧 1靠近弹子锁芯模块的一端顶紧着可动锁片 3的左端。 所述使用钥匙的机械式密码复合锁具满足以下要求之一:
在拨盘 4和与之相邻的锁片 6之间设置有套装在轴向凸台 901上并相 对于轴向凸台 901周向固定的卡簧 5;
在锁体 9与和与之相邻的锁片 6之间设置有套装在轴向凸台 901上并 相对于轴向凸台 901周向固定的止动片 8,其具体为片状结构,其外径小于 等于与之相邻的锁片 6的外径;
在锁体 9上距离锁具轴线大于轴向凸台 901外径且与止动片 8相接触 的锁体 9的轴向侧面上设置有 1〜6个弹簧孔 10, 每个弹簧孔 10内都设置 有一个用于保证相互接触的止动片 8和锁体 9之间保持一定轴向斥力的压 簧 11。 所述使用钥匙的机械式密码复合锁具满足以下要求:
所述使用钥匙的机械式密码复合锁具的锁体 9靠近钥匙进口端的端面 上设置有固定在其上的密码盘结构。 本发明的一个突出特点是: 钥匙 14带动锁芯 12转动, 同时钥匙 14将 可动锁片 3沿锁具轴向向远离锁体 9的方向顶紧,使得可动锁片 3与拨盘 4 内孔的卡槽契合相对轴向固定, 从而实现可动锁片 3带动拨盘 4转动的关 系; 最远离钥匙进口端的锁片 6在拨盘 4借助于拨销 13的作用下顺序带动 各个锁片 6转动; 最靠近锁体 9的锁片 6最先被调整到开锁状态; 当所有 锁片都被调整到开锁状态时, 锁具开启。
当钥匙 14从锁芯 12中拔出时, 在弹簧 1的作用下可动锁片 3向靠近 锁体 9的方向复位, 可动锁片 3与拨盘 4内孔卡槽的契合脱开, 二者相对 轴向固定的关系解除。如果借助于一般的开锁工具, 不能拨动拨盘 4, 从而 不可能实现开锁。
如果借助于开锁工具勉强使得拨盘 4带动与之相邻的锁片 6转动达到 开锁状态, 开锁者想要在此锁片 6位置不变的前提下继续开锁是不可能的。 因为下一级锁片 6必须借助于上一级锁片 6才能转动并最终到位。
即使开锁者准备了原装钥匙 14, 但是如果他不知道开锁密码, 是不可 能在可操作的短时间内试出密码并实现开锁的。 其完全可能和上一段中的 情况一样。 本发明将机械式密码锁和用钥匙开启的机械式弹子锁创造性地采用一 种全新的方式复合在一起, 将机械密码模块设置在锁具远离钥匙进口端的 部位以便对其进行较好的保护; 本发明使用钥匙 14作为唯一的开锁工具, 开锁手段相对简单, 容易操作; 内层的机械密码装置不容易被解密或破坏; 其安全性明显提高; 技术效果明显好于现有技术。

锁片 6为 3片, 在相邻的两个锁片 6的相邻的两个侧面上设置有与锁 具轴线基本等距的拨销 13。拨销 13用于当一个锁片 6主动转动时借助于拨 销 13拨动另一个锁片 6随之转动。 所述使用钥匙的机械式密码复合锁具中, 在相邻的两个锁片 6之间设 置有分隔止动垫片 7,所述分隔止动垫片 7为内部有孔的片状结构, 内部圆 孔内径不小于可动锁片 3宽度最宽处的尺寸;
所述使用钥匙的机械式密码复合锁具中, 弹子锁芯模块的主体为外径 相对较大的锁体 9,其内部设置有钥匙孔;锁体 9靠近锁片 6—侧设置有与 锁具同轴线的轴向凸台 901,该轴向凸台 901为空心管状结构,弹子锁芯模 块的锁芯 12设置在上述的轴向凸台 901内部并能绕锁具轴线转动;
所述弹子锁芯模块的锁芯 12靠近锁片 6—端设置有与可动锁片 3构成 二者周向固定的配合结构; 同时, 该配合结构与钥匙孔连通, 当钥匙孔中 有钥匙插入时, 插入的钥匙轴向顶紧可动锁片 3使其轴向串动并形成可动 锁片 3与拨盘 4的周向同步转动关系并进而实现开锁动作。 所述使用钥匙的机械式密码复合锁具中, 锁片 6设置在拨盘 2靠近锁 体 9的一侧;
所述拨动模块中的拨盘 4为分体结构, 其主体部分为内部有孔的片状 结构, 其内部圆孔内径不小于可动锁片 3远离弹子锁芯模块的宽度较小部 分的宽度, 其内部圆孔内径小于可动锁片 3靠近弹子锁芯模块的宽度较大 部分的宽度;

当钥匙 14从锁芯 12中拔出时, 在弹簧 1的作用下可动锁片 3向靠近 锁体 9的方向复位, 可动锁片 3与拨盘 4内孔卡槽的契合脱开, 二者相对 轴向固定的关系解除。如果借助于一般的开锁工具, 不能拨动拨盘 4, 从而 不可能实现开锁。
如果借助于开锁工具勉强使得拨盘 4带动与之相邻的锁片 6转动达到 开锁状态, 开锁者想要在此锁片 6位置不变的前提下继续开锁是不可能的。 因为下一级锁片 6必须借助于上一级锁片 6才能转动并最终到位。
即使开锁者准备了原装钥匙 14, 但是如果他不知道开锁密码, 是不可 能在可操作的短时间内试出密码并实现开锁的。 其完全可能和上一段中的 情况一样。 本实施例将机械式密码锁和用钥匙开启的机械式弹子锁创造性地釆用 一种全新的方式复合在一起, 将机械密码模块设置在锁具远离钥匙进口端 的部位以便对其进行较好的保护; 本实施例使用钥匙 14作为唯一的开锁工 具, 开锁手段相对简单, 容易操作; 内层的机械密码装置不容易被解密或 破坏; 其安全性明显提高; 技术效果明显好于现有技术。 实施例 2
